I tried but anyway the connection print the data received to my C# console and not the bangle. I tried even by deactivating the console with the code below, same results:

setInterval(() => (console.log(E.getTemperature())), 1000);

g.setFontAlign(0,0); 
g.setFont("Vector",25);
var gatt;

E.setConsole(null);


NRF.on('connect', function(addr) {
  g.clear();
  g.setFont("Vector",10);
  g.setColor(255,0,0);
  g.drawString(addr,g.getWidth()/2, g.getHeight()/2);
  g.setFont("Vector",25);
  setTimeout(()=>g.drawString("Connected",­ g.getWidth()/2, g.getHeight()/2), 3000);
  setTimeout(()=>g.clear(), 1000);
});

NRF.on('disconnect', function(reason) {
  g.clear();
  g.setColor(0,0,255);
  g.drawString("Disconnected", g.getWidth()/2, g.getHeight()/2);
  setTimeout(()=> g.clear(), 1000);
});



Bluetooth.on('data', function(d) { 
  g.clear();
  Bluetooth.println(d);
  g.setColor(0,0,0);
  g.drawString('Data received', g.getWidth()/2, g.getHeight()/2);
  g.drawString(s); 
  g.drawString(s, g.getWidth()/2, g.getHeight()/2); 
});

this is instead the C# console class:

Any other suggestion?

No actually I didn't call the E.setConsole(), I'll try even if I'd like to keep the console on my logic to double check the response. As for your first suggestion, did you mean to implement a callback function 'X' which will accept the data sent as parametr and which is call when something is received? Basically adding this function within Bluetooth.on()?

Hi,
I'll remove the line of code concerning the

writer.WriteByte(0x01);

and test as you suggest!
This is instead my js code running on Bangle:

g.setFontAlign(0,0); 
g.setFont("Vector",25);
var gatt;
NRF.on('connect', function(addr) {
  g.clear();
  g.setColor(255,0,0);
  g.drawString("Connected", g.getWidth()/2, g.getHeight()/2);
  setTimeout(()=>g.clear(), 1000);
});

Bluetooth.on('data', function(d) { g.drawString(d, g.getWidth()/2, g.getHeight()/2); });

NRF.on('disconnect', function(reason) {
  g.clear();
  g.setColor(0,0,255);
  g.drawString("Disconnected", g.getWidth()/2, g.getHeight()/2);
  setTimeout(()=> g.clear(), 1000);
});

Is Bluetooth.on() called once the BLE received packets ?

Hi! Thanks for your prompt repyl: where can I find reference to the

Bluetooth.on('data', function(d) { ... })

method? I couldn't find anything on the doc. Anyway, regarding the first method, do you think this is correct in my c# console? This is just a test:

else if (properties.HasFlag(GattCharacteristicPr­operties.Write))
                                        {
                                            Console.WriteLine($"\t \t Characteristic {characteristic.Uuid} has a write property ");
                                            Console.WriteLine("---------------------­----------- ");
                                            var writer = new DataWriter();
                                            // WriteByte used for simplicity. Other common functions - WriteInt16 and WriteSingle
                                            writer.WriteByte(0x01);
                                            writer.WriteString("\\x10X({my:\"data\"}­)\\n");

Hi there,
I am implementing a BLE connection between my pc and the Bangle js 2 to stream data from the Bangle to the pc and send back responses to the bangle. I successfully managed to connect the two devices (the bangle is acting as a server device streaming the data I need to a C# console), but I'd like to send back a response string. Data is wrapped in my C# and sent to the bangle but I cannot find a way to read it on the device: do I need to create a specific characteristic on my pc to which connect the bangle or am I missing something? Connection actually is successfull but is it biunivocal?
Thanks in advance!

I just uploaded the Icon.js to my bangle storage through the web Ide but on calling require("Icons.js") no module is found. Any suggestion?

Thanks Gordon for your reply, always a prompt one! I'll try what you suggested! I uploaded to the local storage but when I try to retrieve the module I am not able to. I'll check again!

Hi guys,
I'm encountering problems in implementing my own custom module for the Bangle js 2. I have a public Github repo where I am uploading my code, but the web Ide continues on saying that my modules do not exist. Here my example code.

var happy = require("https://github.com/riccardokhm/­Human-Monitoring-Technologies/tree/main/­Projects/Bangle%26Puck%20Js/Modules/Icon­s.js");
console.log(happy._happyIcon);

Moreover, I have no possibility from my Web Ide of loading the module from a local folder:any suggestion?

Thanks in advance!

Thanks, solved! I'm new to js and trying to make thing with sense! Just a last question: is there the possibility to use "import" with the Bangle.js to refer to other namespaces o scripts?

Thank you a lot! What if I'd like to make the image appear only for some time and then clear the screen? is there any built in method to use?

Hi folks! I'm trying to draw an Image on my Bangle Js 2 screen when a threshold on my HR is overcome: please find attached my code. Basically, the screen is lightining up but it seems like no time is left to draw the image on screen. Is it due to asynchronous execution of code? Any suggestion?

Thank you so much! I’ll let you know more if I’ll be able to succeed. Actually we would like to integrate the bangle 2 too. Is it feasible in case to provide the Puck with a small motor for vibration alerts?

Hi guys,
I'm trying to use acc and gyro data to reconstruct a human manikin of the user, have you ever tried to do something similar or do you have any suggestion?
Thanks in advance!

Thanks, yep actually I'm looking for C# console app, so that's perfect. Have you tried to integrate bangle.js app with Windows?

Hi there,
I'm looking for a fast-implementing way of connecting and communicating with my bangle.js 2 and a windows app, do you have any suggestions on any .dll or library to use?
Thanks in advance
